“…Imperfect osseointegration can cause aseptic loosening which is the main cause of hip replacement implant failure (76%) [3], [4]. Ideal osseointergation can be achieved on implant surfaces with roughness of micrometers (> 100nm) better than nanometer sizes (<100 nm) in terms of cell adhesion [5] and implant stability [6]. Micro roughness also lessen the possibility of copper contamination that could induce toxicity [7], [8].…”

Osseointegration is a process consisting of the formation of bone tissue on the implant surface, so that the osseointegration process occurs, a surface with surface roughness (Ra) is required in isotropic microtopography with a size of 1-100 nm. The plasma treatment can be done to reach the Ra parameter. This study aims to discuss the treatment of Plasma Electrolytic Process (PEP) with the principle of physiochemical erosion using electrolytic cells on Ti-6Al-4V alloy implants, to form a plasma layer in the form of spark discharge and Vapour Gas Envelope (VGE). Samples made of Ti-6Al-4V are tested with several parameters including different electrolytes and different applied voltages are investigated, and the results of the formation of VGE which influences the surface characterization are evaluated. The results show that the process of PEP with electrolyte consist of 50% H3PO4 + 10% NaClO4 + 1% HF and 10% ethylene glycol + 2% NH4F at a voltage of 90-130 V produces VGE and non-homogeneous spark discharge resulting in a surface with microporous structures with increasing surface roughness and micro-hardness indicating the formation of an oxide layer.

“…Ti-6Al-4V which has higher mechanical strength, young modulus almost equal to human bones thus reducing the shielding effect, extending the life of implant material, and non-toxic. [1] Problems that arise in implant production are the success parameters of titanium implants indicated by the effectiveness of interactions between biomaterials and tissues, influenced by several factors, including the composition of implant surfaces, implant morphology, and roughness of implant surfaces [2,3]. Implant failure still occurs, Mechanical loosening, until the infection associated with this implant still poses a serious threat that leads to possible complications such as prolonged hospitalization, complicated revision procedures, implant failure, complete removal, patient suffering, to financial burden [4].…”

Titanium and its alloys are standard for orthopedic prosthetic devices, due to their good mechanical properties and biocompatibility. However, bioactivity on the implant surface needs to be improved to achieve an optimal osseointegration process. Metal implants are often coated by hydroxyapatite because they have a chemical composition and crystal structure similar to apatite in the human skeletal that suitable for bone reconstruction. The focus of this research is on surface treatment designed to promote better biological responses through hydroxyapatite layers. Also combining the acid etching treatment of Ti-6Al-4V and the electrophoretic coating process of the hydroxyapatite to obtain stronger mechanical interlocking interface. Hydrofluoric-Acid treatment conducted in various time. Then, coated with nanosized hydroxyapatite through electrophoretic deposition at 15V voltage for 10 minutes. Scanning Electron Microscopy and Contour measurements were performed to show the surface topography indicating the formation of surface contours with increasing surface roughness parameters in accordance with the time of the etching process. The contours on the surface of the substrate induce the mechanical interlocking of the surface so that the results of hydroxyapatite deposition optimal at the time of etching 5 minutes
